Environmental science and engineering 2025
Yinian Zhu, Sijia Yang, Kai Yang, Ming Zhao

Summary

Researchers compared the performance of municipal wastewater treatment processes in China and Sweden at removing microplastics, finding that while conventional plants remove a significant portion, effluent still carries microplastics into receiving waterways. Advanced treatment steps like membrane filtration and sand filtration showed better removal rates, suggesting infrastructure upgrades could meaningfully reduce pollution.

Study Type Environmental

Microplastic in waste water and performance of WWTP (Wastewater treatment plant) in China is presented and compared with other studies mainly from Sweden. The commonly used treatment processes in municipal wastewater treatment plants are introduced and compared...
